Short Selling
The Formal Definition
An investment strategy that speculates on the decline in a stock's price by borrowing shares from a broker, selling them on the open market, and buying them back later at a lower price to return to the lender.
Profit/Loss = (Sale Price - Repurchase Price) - Borrow Fees
Cole Barrett's Reality Check
The Unvarnished Bottom Line"Short selling has an asymmetrical risk profile that terrifies sensible investors: your upside is capped at 100%, but your potential loss is mathematically infinite. If you get caught in a short squeeze, the broker will buy you in at the absolute peak."

How Brokers Weaponize This Term
Brokers charge fluctuating 'Hard-to-Borrow' (HTB) rates that can skyrocket from 2% to 150%+ annually overnight, bleeding short positions dry via daily borrow fees.
